In the northern Kyushu, The Ariake clay, i.e. the soft marine alluvial clay, is sedimented along the Ariake Sea. It is well-known as one of the most problematic soils in Japan, because of its high sensitibity and remarkable secondary compression. The aim of this paper is to offer the basic information about the current feature of designs and executions of infrastructures and trends of countermeasures on the soft clay grounds in Japan in always comparison with Ariake clay ground. The steps of the paper are first literature references and research in past ten years and secondly questionnaire to the local government offices around the Ariake Sea. The paper describes some of most effective methods of designs, executions and countermeasures of infrastructures on the Ariake soft clay grounds after the analysis of both literature references and questionnaire., 長崎大学工学部研究報告 Vol.26(47) p. 287-294, 1996}, pages = {287--294}, title = {我が国の海成土地盤および有明粘土地盤の設計・施工事例の調査・分析}, volume = {26}, year = {1996} }
